- Abstract
- We have utilized spatially resolved low temperature photoluminescence to probe the electronic states and structural symmetries of individual single crystalline CdS nanosheets. Spatially resolved photoluminescence imaging of a single CdS nanosheet reveals a distinctive spectral variation across the nanosheet. We observe A-like exciton states which emit most strongly near the outer edges of the 5 mu m wide nanosheet, while B-like exciton states emit most strongly along the center region of the 30 mu m long axis of the nanosheet.
